If you research permanent-jewelry welders for more than an afternoon, one name keeps surfacing: Sunstone. It's a US-based welder manufacturer whose permanent-jewelry line has become the reference point for working operators, and for a practical reason: its machines are made and supported in the USA, carry a 3-year warranty, and keep replacement electrodes in stock. When a weld fails in front of a paying customer, being able to call a human is worth real money, and that support network is a big part of what the Sunstone premium buys.
Sunstone sells three permanent-jewelry welders. They're not variations on one machine so much as three answers to three budgets and volumes: the entry Zapp, the full-range value Zapp Plus 2, and the touchscreen flagship Orion mPulse. This guide places each one, then hands you to the full review.

The single spec that separates them is energy range, which decides which metals each can weld. The Zapp covers gold-filled and fine chain; both the Zapp Plus 2 and mPulse reach the full 1-30 joule standard-metal range, and the mPulse then adds a touchscreen and finer control on top.

Which Sunstone is right for you
- Start on gold-filled and fine chain, tightest budget → Sunstone Zapp. Around $1,249, the simplest way onto the platform. Its 3-10 joule range is only a limit once you move to heavier metals.
- Want the full metal range at the best value → Zapp Plus 2. The full 1-30 joule range and a lock-in digital dial in the lightest (1.9 lb) Sunstone, from around $1,699. That is the range of the flagship without the touchscreen premium.
- High volume, mixed metals, events all day → Orion mPulse. The touchscreen, Tru-Fire Technology, and 0.5-joule fine steps speed up a busy studio, from around $2,999.
There's also a first-generation Zapp Plus bundle sold on Amazon, a genuine Sunstone build with an Amazon checkout, if you'd rather buy with Prime shipping and easy returns. And if you're open to a non-Sunstone machine, the dial-based Pepetools Helix reaches the same 1-30 joule range for around $1,499 — Helix vs Zapp Plus 2 is the direct comparison.

Sunstone welder FAQ
Who is Sunstone Welders?
Sunstone is a US-based welder manufacturer whose permanent-jewelry line is the brand most working PJ artists cite. Its machines are made in the USA and backed by US-based customer service and a 3-year warranty, which is a large part of why operators pay a premium over generic imports: you can reach a human when a weld fails at a paid event.
Which Sunstone welder is best for beginners?
The entry Zapp, at around $1,249, is Sunstone's beginner machine: a simple dial, a 3-10 joule range that covers gold-filled and fine chain, and the same US warranty and support as the rest of the line. If you already know you'll weld heavier and mixed metals, the Zapp Plus 2 adds the full 1-30 joule range for a modest step up.
What is the difference between the Zapp Plus 2 and the Orion mPulse?
Both reach the full 1-30 joule range. The mPulse adds a touchscreen, Tru-Fire Technology, and finer 0.5-joule steps below 15 joules, aimed at high-volume studios; the Zapp Plus 2 delivers the same range with a digital dial in a lighter (1.9 lb), cheaper package. The premium buys interface and fine control, not more range.
Are Sunstone welders worth the price over Amazon machines?
For a working business, usually yes. A budget Amazon pulse-arc welder is the cheapest way to test whether permanent jewelry is for you, but a Sunstone earns its higher price through consistent welds, in-stock electrodes, a 3-year warranty, and US phone support you can reach mid-event. Many operators start on a budget machine and reinvest into a Sunstone once sales prove the model.
